If the Mets can't get a good deal for Beltran, they might as well just keep him and see what happens for the Wild Card chase. While it might not make sense for other teams to give up top prospects for a rental, it might make less sense for the Mets to give him up for nothing. If anything, if the Mets can improve their pitching (especially starting), they could conceivably make a run at the Wild Card. That makes the return of Santana this season all the more interesting and relevant.
